What the Rako RK-PIR is
The Rako RK-PIR is Rako's own wireless presence sensor. For third-party PIRs, use the RAMVR interface instead; the WK-PIR is the wired-system sensor.
Where it sits in a Rako system
The RK-PIR runs in Hub managed mode: it is added in RASOFT Pro and configured on the RK-HUB web pages before installation, with a RAMPI used for pairing. Its modes can be limited to set times or to dawn and dusk. See all Rako wireless interfaces.
